“…The adsorption of MOF toward the target is theoretically influenced by the strength and type of molecular interaction, accessibility (orientation or pore distribution), and application forms (equilibrium or nonequilibrium). 44,45 In this work, the surface area played a secondary role. Using the above analysis of interaction force, it was the hydrophobic interaction provided by the benzene ring that contributed the most.…”

Composite adsorbents based on metal−organic frameworks (MOFs) are excellent candidates for solid-phase extraction (SPE) due to their diverse chemical functionality and multilevel porosity. MOF superstructures based on self-assembly at room temperature (RT) could have less energy consumption and easier manipulation due to the larger complex geometry. The π−π stacking of the benzene ring could not only enhance the interaction toward hydrophobic or plane-structured targets but also be expected to promote the formation of the MOF superstructure. In this work, in the established RT self-assembly synthesis system, several factors were investigated to see how to obtain functional MOF superstructures with a regular geometry, among which the number of benzene rings in the ligand was mainly tested for its impact on selfassembly and adsorption capacity. By means of adsorption experiments and computational fluid dynamics (CFD) simulation, the relationship between structure and activity (SARs) was further explored. Interestingly, the MOF unit with the lowest specific surface area performed the best in adsorption. Then, the selected functional MOF superstructure and ionic liquid were used to produce the composite paper membrane facilely applied in the SPE device. After optimization of the preparation conditions and operation parameters, the established SPE-HPLC-UV method could selectively analyze tetracycline-like antibiotics in the range of 16.6−833.3 ng/g (ppb) in a meat sample. This work provided an RT synthesis method to produce a microsize MOF superstructure, with experimental and theoretical insights into the SARs, which could be expanded in the design of other MOF-based SPE composite membranes toward one group of analogues.

“…Recent trends in sample preparation include miniaturization of classical extraction techniques, getting generally simpler, faster and greener techniques, a miniaturized SPE method, such as pipette tip solid-phase extraction (PT-SPE) by packed adsorbent has been developed (Ning et al 2022;. In PT-SPE, the choice of adsorbent materials is a decisive factor (Yu et al 2021) to determine the extraction e ciency and performance. Conventional adsorbents, such as C18, silica, and NH 2 are unable to meet the current needs of sample preparation because of a single adsorption mechanism, poor selectivity, and low adsorption capacity (Yuan et al 2015).…”

Azo-linked porous organic polymers (APOPs) were synthesized by a simple azo reaction, with 2,2'-bis(trifluoromethyl)benzidine and 1,3,5-trihydroxybenzene as the monomers. The preparation process was mild, green and environmental-friendly, avoiding the use of high temperature, metal catalysis and harmful organic reagent. The obtained APOPs were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, powder X-ray diffraction and Brunauer-Emmett-Teller. With the prepared APOPs as adsorbent, a method of pipette tip solid-phase extraction-liquid chromatography tandem mass spectrometry detection (PTSPE-LC-MS/MS) was proposed for the analysis of target sedatives in animal tissues. Furthermore, the parameters for the extraction of five sedatives, including the amount of adsorbent, pH value, ion strength, elution solvent and volume, were investigated. Under the conditions optimized, the linear dynamic range was found from 0.1 µg kg− 1 to 10.0 µg kg− 1, and the limits of detection were ranged from 0.02 µg kg− 1 to 0.1 µg kg− 1. The method was assessed by the analysis of target sedatives in animal tissues, and the recoveries for the spiked pork samples and egg samples were 84–102% and 83–101%, respectively. The results show that the developed method of PTSPE-LC-MS/MS with APOPs as adsorbent is efficient for the analysis of trace sedatives in animal tissues.

“…3 Thus, rapid discrimination of isomers is of utmost importance for practical applications. Several approaches have been widely used to recognize isomers including chromatography, 4,5 electroanalysis, 6,7 spectrometry, 8,9 voltammetry, 10,11 and capillary electrophoresis. 12,13 However, these methods are unable to provide a solution for point-of-care applications ranging from single-use diagnostics to microanalysis.…”

“…The theoretical modeling predicted that the observed fluid flows were predominantly driven by solutal buoyancy, and the higher velocity output of L-Trp indicated its higher affinity as compared to D-Trp for the ''host'' site due to favourable molecular orientation. To extend the scope of this approach, a pillar [5]arene-based interface was used to discriminate the constitutional isomers of nitrophenol. The fluid flow was observed only in the case of p-nitrophenol (p-NP), whereas onitrophenol (o-NP) did not produce any fluid flow because of the cavity size mismatch with pillar [5]arene.…”
